Abstract: ABSTRACT  OF  THE  DISCLOSURE     An entrapment assembly for use in a flying disc golf game.  The entrapment assembly in one of its embodiments comprises an upright post mounted in the ground.  An upwardly opening basket is mounted on the post and a plurality of outside chains are mounted on the post so that the lower ends thereof extend into the basket.  The outside chains serve to absorb kinetic energy from a disc thrown against the assembly and thereby reduces its forward velocity.  A disc deflection surface, such as a group of inside chains, extend outwardly and upwardly from a location adjacent the top of the basket to deflect the disc toward the basket after it has impacted the outside chains to ensure that the disc is caught in the basket.

Abstract: BACKGROUND OF INVENTION (ABSTRACT) This invention relates to the use of play instruments used in psycho-therapy with children to assist in; 1.  The gathering of background information. 2.  Assessment of emotional/social problems, and 3.  treatment through the use of structured play.    Hitherto play-therapy houses have been adapted from less app-ropriate commercially available doll houses of fragile construction or from disposible materials (cartons, boxes) not specifically ident-ified as houses.  Where sturdy, large and appropriate play-therapy houses are used they require large areas permanently allocated for their use.

Abstract: ABSTRACT OF THE DISCLOSURE         A photopolarimeter for the simultaneous measurement of all four Stokes parameters of light.  The light beam, the state of polarization of which is to be determined, strikes, at oblique angles of incidence, three photodetector surfaces in succession, each of which is partially specularly reflecting and each of which generates an electrical signal proportional to the fraction of the radiation it absorbs. A fourth photodetector is totally light absorbing and detects the remainder of the light.  The four outputs thus developed form a 4x1 signal vector ? which is linearly related, ? = ??, to the input Stokes vector ?.  Consequently, ? is obtained by ? = ? -1 ?.  The 4x4 instrument matrix ? must be nonsingular, which requires that the planes of incidence of each of the light beams are all different.  For a given arrangement of four detectors, ? can be either computed or determined by calibration.

Abstract: ABSTRACT OF THE DISCLOSURE          A bumper for a dolly or hand cart includes a protective outer surface portion which extends around the outer side of the cart frame to protect against damage in the event of a collision.  The frame supports a container such as a cylindrical tank.  Connected to the outer sur-face portion at each of its ends is a securing element which includes a horizontal portion extending over a sec-tion of the cart frame below the container.  At the inner end of the horizontal portion is a locking portion which may extend downward along the inner side of the cart frame.  Because the securing element extends between the frame and the container, the weight of the container pre-vents removal of the bumper.  Vertical ribs between the protective outer surface portion and the frame provide rigidity to the bumper and absorb the impact upon occur-rence of a collision.

Abstract: DOCKET R4386.01 BEAM STEERING UNIT REAL TIME ANGULAR MONITOR     ABSTRACT OF THE DISCLOSURE     Proper operation of a beam steering unit for a phased array antenna, is verified by simulating the pattern of wave energy which would be radiated to an observation point in space when the beam steering unit is connected to phase shifters associated with elements of the antenia.  The simulated pattern thus obtained may be compared with a preset pattern for the observation point during a scanning operation of the beam steering unit, and an alarm or other indication is obtained when the difference between the simulated and the preset pattern exceeds a certain limit.  The simulated pattern is obtained by storing phase angle data from the beam steering unit in a memory at areas corresponding to phase shifters associated with elements of the phased array antenna.  The memory areas are incremented from initial phase angle data corresponding to the beginning of a scan operation, in accordance with phase angle data provided by the beam steering unit at certain time intervals.  Observation angle data corresponding to the angle of the point in space relative to the antenna array is generated, the observation angle data being a function of observation angle, antenna element spacing and radiation wavelength.  The updated phase angle data is combined at each time interval with the observation angle data, and composite angle data is produced as a function of the combined data.  From the composite angle data for each time interval, is subtracted the composite angle data for the immediately preceding time interval, and the resulting differences are accumulated with initial value composite angle data to produce a running accumulation of composite angle data in real time.  The relative amplitude of wave energy which would be observed at the point in space during a scanning operation of the beam steering unit is then determined as a function of the accumulated composite angle data in real time.
